Abstract

Brazil recorded approximately 8.8 million vulnerable animals between 2018 and 2020, overwhelming NGOs that face limited resources and precarious sanitary management. This scenario favors the spread of parasitic diseases, particularly those caused by pathogens such as Ancylostoma spp. and Trichuris sp. A study conducted in shelters in São João da Boa Vista (SP) and the surrounding region identified Ancylostoma spp. as the most prevalent parasite (50.98%). When comparing the Willis-Mollay and Faust et al. diagnostic methods, Kappa statistical analysis revealed poor to fair agreement between the techniques. These findings demonstrates that the combined use of diagnostic methods is essential to ensure greater accuracy in parasite detection. The results reinforce the urgency of implementing effective sanitary protocols, including periodic deworming and environmental management measures. The objective of this study is to compare the sensitivity and specificity of Faust et al. and Willis-Mollay methods and differentiate them in the diagnosis of  parasites in shelter dogs.
